Interstellar Travel III: Antimatter to the Rescue?

Researchers say millimeter-scale sensors and light sails could let tiny probes reach nearby stars within a human lifetime.

Summary by Universe Today
With the end of the Space Age and the winding down of the Cold War, scientists again returned to the question of interstellar flight. Having failed to realize a working concept that could be realized in the near term, more exotic ideas began to be considered, reflecting further breakthroughs in theoretical physics.

Matter-antimatter annihilation is a fundamental concept in modern physics, with significant implications for space propulsion. This phenomenon occurs when a particle of matter collides with its corresponding antiparticle, resulting in an energy release equivalent to that of a thermonuclear bomb. Exploring this process could open new possibilities for interstellar travel. The concept of matter-antimatter annihilation involves the interaction of p…
